Grillad biff med tomater, rödlök och balsamico

👩‍🍳 Gör så här

1. 1
   Pierce steak all over with a fork. Season generously with 1 1/4 teaspoons kosher salt, pepper and garlic powder and set aside about 10 minutes at room temperature.
2. 2
   In a large bowl, combine onions, olive oil, balsamic, 1/4 teaspoon salt and pepper. Let onions sit a few minutes in the mixture to mellow a bit. Combine with tomatoes and fresh herbs and adjust salt, if needed.
3. 3
   Heat grill or broiler on high heat. Cook steak about 7 minutes on each side for medium rare or longer to taste. Remove from grill and let it rest on a plate for about 5 minutes before slicing.
4. 4
   Slice steak thin on the diagonal; top with tomatoes and serve.
